Understanding Cobb AP Reflash vs Realtime

According to the Cobb Access Port Manual:

Realtime: The AccessPORT can upload a calibration for immediate use. The
calibration will remain in the ECU until the ECU loses power or is reset.

Reflash: Permanent reflash of the calibration onto the ECU. The AccessPORT will
request for the vehicle to be placed in ECU reprogramming mode. Follow the onscreen
prompts to complete this step

Which map to use?

According to research done online: Is better to keep the car with basemap that matches mods and fuel then pick a realtime on top of that. So I should be using Stage 1 91 base/reflash and then Stage 1 93 realtime. But because I use 93oct pretty much all the time I left my base map and realtime Stage 1 93 oct. ( I will try the 91 map after I empty this tank)
